只有当我在gradle文件中添加starter-web时才会出现问题：
....
dependencies {
compile('org.projectlombok:lombok')
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-devtools')
compile('io.springfox:springfox-swagger2:2.5.0')
compile('io.springfox:springfox-swagger-ui:2.5.0')
runtime('mysql:mysql-connector-java')
}
....
application.properties
# Connection url for the database
spring.datasource.url = jdbc:mysql://localhost:3306/alledu?useSSL=false
# Username and password
spring.datasource.username = user
spring.datasource.password = pass
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
THX任何帮助 - 我有点绝望

您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在'选项附近使用正确的语法（id bigint not null auto_increment，value varchar（255），poll_id bigint，p'在第1行
option是MySQL 5.7中的关键字和保留字，您可以参考Table 10.2 Keywords and Reserved Words in MySQL 5.7
